Congress ordered the list to be compiled in response to Russia's meddling in the 2016 presidential election, asking for "a detailed report on senior political figures and oligarchs in the Russian Federation ... and on Russian parastatal entities."

On Tuesday, it was reported that the list was compiled from open sources, mainly a Forbes article of the 200 richest Russian businessmen.

When asked why the list was of the richest Russian businessmen, and not oligarchs suspected of corruption, the Treasury Department told Business Insider in an email that the "report complies with requirements" of the law, adding that there's also a classified portion.

Based on the Treasury Department's list and Forbes' data on each of the Russians' current individual wealth, we've rounded up the 25 richest Russian oligarchs from the "Putin list:"

25. Andrey Kozitsyn: $4.8 billion

24. Dmitriy Kamenshchik: $5 billion
